...IP following the documentation and sample code's. I am facing audio glitches when encoding - decoding PCM data. The encoder and decoder procedures are copied below. What about the lookahead size ? how shouw we apply it in encoding stage ? thanks in advance bool SpeexEncoder::EncodeData(char * inBuffer, int inSize, char * outBuffer, int outMAXSize, int* outSize) { if(!m_Initialized) return false; // Copy data into the local buffer memcpy(m_pBuffer + m_BufferSize, inBuffer, inSize); m_BufferSize += inSize; // check if we have enougth data for the encoder, if(m_BufferSiz...

...and mode, this > corresponds to a buffer size of 160 samples. Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte each that I put in a RPT payload of 80 bytes: UINT CSpeexCodec::Encode( float *inBuff, const char**outBuff, UINT BufferFrames ) { speex_encoder_ctl(spx_state_, SPEEX_GET_FRAME_SIZE, &spx_frame_size_); while (BufferFrames>0) { speex_bits_reset(&spx_bits_); speex_encod...

...The end-result is very distorted sound. I use the following PCM format: waveFormat.nChannels = 1; waveFormat.nSamplesPerSec = 8000; waveFormat.wBitsPerSample = 8; Once sound is aquired by the mic, I send it to Speex in a Char buffer. It looks something like this: Encode(char* inBuffer, DWORD bufferLength) ... float* input = new float[frameSize]; ZeroMemory(input, frameSize); ... for( ) { input[..] = inBuffer[..]; } ... speex_encode(enc_state, input, &bits); int bytesWritten = speex_bits_nbytes(&bits); speex_bits_write(&bits, encBuffer, bytesWritten);...

Hi, in a VoIP application, the endpoint A send speex payload to B. B doesn't know how A acquire audio, it only know that the channel is narrowband so, how can B know the size of the output buffer to pass to the speex_decode()? Thanks, Daniele.
